' CAR-BODY BOLSTER.

SPECIFICATION forming part of Letters Patent No. 776,236, dated November29, 1904.

Application filed June 3,1904. Serial No- 210,939. (N model.)

To all whom, it may concern.-

Be itknown that I, JOHN GREEN, a citizen of the United States, residingin the city of St. Louis, in the State of Missouri, have inventedcertain new and useful Improvements in Oar- Body Bolsters, of which thefollowing is a full,

clear, and exact description, reference being had to the accompanyingdrawings, forming part of this specification.

My invention relates to a body-bolster for railway-cars, the object ofthe improvement being to provide a construction of bolster through whichany size of draft-sills may be introduced to be finally positioned andsecured in 'place in the bolster without necessity of furnishing anyholding means for the sills other than those carriedv by the sill whenit is passed through the bolster.

Figure I is a top or plan view of my bolster. Fig. II is a sideelevation of the bolster. Fig. III is a longitudinal horizontal sectiontaken on line III III, Fig. II. Fig. IV is a vertical cross-sectiontaken on line IV IV, Fig. I. Fig. V is a vertical cross-section taken online V V, Fig. I. Fig. VI is a side view of a modification.

The main body of my bolster consists of a' vertical web 1, surmounted bya top chord. 2 and having beneath it a bottom chord 3. The bottom chordcarries a center bearing 4 and side bearings 5. The web 1 is reinforcedat the location of the side bearings by enlargements 6. In the web abovethe center bearing of the bolster and beneath the top chord 2 is anopening 7, and at the central portion of this opening is apocket 8 ofgreater depth than the sides of the opening, which terminate at theirbottoms'in draft-sill ledges 9. The draft-sills that are seated in thebolster and which bear lugs or ribs spaced apart to hold them in placein the bolster are first passed through the central portion of theopening 7 so that they will move through the pocket 8, and when they arebrought to the proper position in which they are to be located in thebolster they are lifted and moved laterally onto the ledges 9 at eachside of said pocket to remain on said ledges, when they are secured tothe car-body in the usual manner.

In Fig. VI, I have shown a modification of my improvement, whichconsists'in locating the draft-sill ledges 9 immediately above thecenter bearing 4 of the bolster and providing pockets or depressions 8beyond said ledges toward the end of the bolster to receive thedraft-sills, which on being introduced thereinto are raised and placedon the ledges. The sills are therefore moved toward the longitudinalcenter of the bolster instead of being moved outwardly from its center,in the construction previously described.

I claim as my invention- 1. As a new article of manufacture, a carbodybolster provided with a central opening and having draft-sill ledgeswithin said opening; said opening including a depression beneath theplane of said ledges, substantially as set forth.

2. A car-body bolster having therein a central draft-sill opening,ledges at the lower Sides of said opening; said opening including adepression between said ledges extending downwardly to a plane lowerthan the level of the ledges, substantially as set forth.
